Jill Clarke asked:

There's an old wives tale that a glass of cold milk will help you sleep? Does digestion make you sleepy?


Jason Rihel - So, my experience is, it’s been always a glass of warm milk that makes A glass of milkme sleepier, but yes, there are definitely foods that can make us less tired or more awake. In fact, many people have experienced for example, after a large meal in particular, sleepiness. That's actually a period of sleep called postprandial sleep which is after eating sleep. If you look throughout the animal kingdom, think of the mighty lion for example, feasting on a zebra carcass and then just going off for a big long nap.
